PEEKSKILL, N.Y. – A second person has been charged in Friday’s fatal stabbing of a Peekskill man, according to Peekskill police.

Detectives charged 32-year-old Maurice Walker of Mount Vernon, who already was being held on an unrelated charge, in the slaying of 23-year-old Alexander Rochester. Rochester was a Bronx resident who had recently moved to Peekskill, police said.

Walker was brought Wednesday from the Westchester County Jail to Peekskill City Court for arraignment on a charge of second-degree murder, a class A felony.

Walker, who police said had a feud with Rochester, was charged after detectives analyzed forensic and video evidence. Police said that he acted with 29-year-old Sunil Williams of Mount Vernon and that Williams stabbed Rochester multiple times. The investigation is continuing, although no further arrests are expected.

The following items also were reported by Peekskill police:
